Hello y'all, looking to build a half way decent suspension set-up for fast road and track driving while spending the minimum possible and make use of what I already got, here goes...
The car: '13 GT86, forged bottom end, boosted from a gtx2867 on a 1 bar (14.5psi) minimum setting. Current suspension setup, which I put together for daily street use and dirt road fun: Bilstein B6 shocks, Chuhatsu Multiroad lift springs, SPC front camber bolts, Pedders -camber/+caster top mounts. This year I'd like to do a few track days and local time attack competitions, and a few changes/upgrades are needed.
I'm thinking of keeping the B6 dampers as they are fairly new (put around 3000 miles on them) and pair them up with some stiffer springs. The plan is to use coilover conversion sleeves which I already have and adjustable coilover springs, for which I already found a supplier that has them in tapered shape and with the correct diameters to fit with oem style upper mounts. My questions are, what spring rate should I go for and what's the max spring rate these B6's can handle? Would 6kg/mm both front and rear be to much for them?
With the springs that I'm going to install, I'd like to keep the ride height as close as possible to stock, maybe even 1cm higher to gain some more bump travel. As for the rest of the setup, I already bought and need to install the Energy master poly-bushing kit and rear camber adjustable LCA's. Will be rollin' on 225 45/R17 DOT semi slicks, unless someone buys my 18" wheels in which case I'll get wider 17" wheels and go for 245mm wide tires. Not planning on changing the anti roll bars for now since most of my budget will get poured into the mandatory safety equipment.
I would also like to experiment playing with anti-squat/traction mod bracket, but in the EU, everything doubles it's cost by the time it gets taxed and shipped so it's not within my budget. Hhere's a long shot though: Anyone that has them installed would care to measure and share by how much is the TCA pick-up point lowered? I can fab them up for a fraction of the cost...
